ab 20 Maii usque ad 21 Iunii.

[Hermes Trismegistus]

Sol transit in hac zona circiter ab 22 Maii usque ad 21 Iunii.

My question is: Should I inflect and pronounce "ab 22 ad 21" as "ab viginti duobus ad viginti unum" agreeing with the preposition in the ablative and accusative respectively when reading?

Are you willing to delve into the black depths of the Roman calendar?

 

[Hermes Trismegistus]

Lol, just a little bit..

It's not too bad, but can be confusing at first:

Viginti duo and viginti unus is not correct. What is needed here is ordinal numbers, and they behave like regular adjectives.

Ordinal numbers, so what would it be like?

ab 22 Maii usque ad 21 Iunii. (ab vicesimo secundo Maii ad vicesimum primum Iunii.)

 

[Dantius]

Yes, however Romans wouldn't have said dates that way anyway.

You count backwards inclusively, like this:
June 1 = Kal. Jun.
May 31 = prid. Kal. Jun.
May 30 = a.d. III Kal. Jun.
...
May 22 would be a.d. XI Kal. Jun. (fully expressed "ante diem undecimum Kalendas Iunias"), and June 21 would be a.d. XI Kal. Jul. (ante diem undecimum Kalendas Iulias). Later authors (like Suetonius and Tacitus) eliminate the "a.d."

The grammar of these date words is hard to understand, but they can be treated as indeclinable nouns. Thus you can say "ab a.d. XI Kal. Jun. usque ad a.d. XI Kal. Jul."

Where's your source from? what link?

 

[AoM]

The video I linked above says the same thing.

ab 22 Maii usque ad 21 Iunii. (ab vicesimo secundo Maii ad vicesimum primum Iunii.)

I understand that you have started this thread to know how ab 22 Maii usque ad 21 Iunii should be read. The above is quite correct, but I would add the word day to it: ab vicesimo secundo die Maii usque ad vicesimum primum diem Iunii. Ab vicesimo secundo die mensis Maii usque ad vicesimum primum diem mensis Iunii is also possible. I think a instead of ab would be better in this case.

that's what I've searched, thanks tibi I ago.
